THE JACKSONIAN OOLOGICAL COLLECTION 
RUFOUS-BREASTED THICKHEAD, 
Pachycephala rufiventris, Latham. 
Taken at South Grafton, Clarence River, N.S.W., by Sid. W. Jackson, on 17th September, 1893. 
Set of 3 eggs. Nest built at altitude of 35 feet, ina Swamp Ti Tree (Me/aleuca.) This species is also 
well known as the Thunder Bird, on account of it repeating its note each time a clap of thunder is 
heard, or a gun is fired in the bush. In fact any sudden noise is immediately followed by a rapid 
succession of notes, lasting about ten or twelve seconds, and which ultimately terminate with sounds 
resembling “ chew-ee, chew-ee, chew-ee,” but which are uttered very slowly. In the Clarence River 
district this bird resorts principally to the small-leaved Ti or Tea Tree (Me/a/euca) during the breeding 
season, and in this tree we have found many of their nests. In Queensland I found them building 
frequently in the Oak trees (Casuarina), about creeks and swamps. Last season (1906) the birds were 
very plentiful everywhere, and they seemed to be in every part of the bush I visited, and by hitting a 
dead tree or log with a tomahawk, very soon brought a clamorous response if they were in the 
neighbourhood. 
Taken at Billy’s Creek, 50 miles south-west of Grafton, N.S.W., by Sid. W Jackson, on 14th 
February, 1900. Set of 3 eggs. 
Taken by W. McKee, at Taree, Manning River, N.S.W., during September, 1890. This pair of 
eggs is of the rare sa/mon color variety, which is to be found in very few collections. The only other 
eggs of this type which I have seen are in the collection of A. F. Basset. Hull, of Sydney, and were 
found at Manly. 
NORTHERN THICKHEAD, 
Pachycephala falcata, Gould. 
Taken at Cooktown, Queensland, by E. Groves, on 12th October, 1895. Set of 3 eggs. Specimen 
A. measures = 0°77 X 0'61. 
WHITE-THROATED TREE CREEPER, 
Climacteris leucophea, Latham. 
Taken from the hollow limb of a tree in Alipou scrub, South Grafton, Clarence River, N.S.W., on 
27th October, 1895, by G. Rowles and Sid. W. Jackson. Set of 2 eggs. We never found many eggs 
of this species in the Clarence River district, and the birds, I find, are more plentiful about Sydney. 
I saw an egg of this species last season (1906), which was found stuck to the bark on the side of a 
Black-butt Eucalyptus, at Roseville, near Sydney. The bird had evidently laid the egg as she was 
climbing on the trunk of the tree feeding, and it was caught in a small portion of bark, which projected 
out just a little from the trunk. It was quite fresh when found. The following beautiful clutch (97) 
of these eggs I found near Sydney. 
Taken from the hollow of a Black-butt Eucalypt (Zucalyptus pilularis), at Middle Harbour, 
Sydney, by Sid. W. Jackson, on 9th November, 1903. Beautiful set of 3 eggs. Specimen A. measures 
in inches = 0'93 X 0°65. 
BROWN TREE CREEPER, 
Climacteris scandens, Temminck. 
Taken from the spout of a tall Iron-bark tree (Eucalyptus stderophiota), at Glen Ugie Peak, 
Clarence River district, N.S.W., on 21st November, 1897, by Sid. W. Jackson. Set of 2 eggs. Very 
difficult climb. I saw many of these birds on Belltrees Station, near Scone, N.S.W., during the end of 
March of this year (1907). 
BLACK TREE CREEPER, 
Climacteris melanura, Gould. 
Taken from the hollow limb of a tree near Cloncurry, Queensland, by a black boy, during 
September, 1891. The birds were identified at the same hollow the next morning. The egg measures 
= 0'87 xX 0°70
